Government Transaction Policy, Media of Exchange, and Prices
在货币搜索模型中研究政府交易政策，将政府视为受相同匹配技术约束的代理人子集，分析其接受交易对象和定价的外生行为如何影响私人代理人策略及均衡集合，并探讨政府规模、货币属性及替代品（如易货或外币）的作用。
We study government transaction policies in search-theoretic models of money. We model government as a subset of agents, who are subject to the same random matching technology and other constraints as private agents, but who behave in an exogenous way regarding which objects they accept in trade and at what price. The objective is to see how these policies affect private agents' strategies, and hence the set of equilibria. We analyze how the effects depend on factors like the size of government, the intrinsic properties of money, and the availability and efficacy of substitutes like barter or foreign currency.Journal of Economic LiteratureClassification Numbers: C78, E31, E42.
